Patent DE-3828308-A1 (DE)
Title: Vehicle brake system with antilock device
Inventor: KAES GUENTER
IPC: B60T8/44
Filed: 1988-08-20
Abstract: In a known vehicle brake system according to the US PS 4655512, in the event of antilock a booster piston using a servo chamber is hydraulically displaced towards its starting position in order to reduce brake pressures, for this purpose two valve arrangements, which have their own actuating solenoids and are therefore expensive, are fitted between the brake booster, the servo chamber and a servo pressure source. In order to reduce the cost of the vehicle brake system, one of the valve arrangements is designed so that it can be hydraulically servo-controlled by pressure variations which are produced in the vehicle brake system (1) by means of the solenoid-operated valve arrangement (45). The hydraulically controllable valve arrangement (49) has hydraulic control inputs (52, 53) for this purpose, which are connected to the servo chamber (37). <IMAGE>

Abstract: A central locking device for a plurality of active function units and/or passive components of a system, such as e.g. of a building, a production system or of a vehicle, is provided with a signal input device for locking and releasing locking elements which are coupled to the function units and/or the system components and react to the input signal. The signal input device (1) consists of a signal generator (2) which can be activated from outside and a data processing device (3). The data processing device (3) is coupled via a serial interface (5) and a bus line (6) to the function units and/or system components (7). The function units and/or system components (7) each have a transmitting/receiving component (10') which can be activated by the input signal as well as a decoding and drive stage (11) for the implemented locking element (31, 43) so that, as a function of an input signal recognised as admissible, the function units and/or system components can be released or locked. <IMAGE>

Title: Communications ear insert
Inventor: MANTEL JUVAL DR ING
IPC: H04R25/00
Filed: 1988-11-18
Abstract: Communications devices such as telephones and radios have the disadvantage that they cannot readily be used in a noisy environment, a free hand is required to operate them and they are uncomfortable over longer periods. The object of the present invention is to enable communication to be carried out with free hands and also in a noisy environment. At the same time, the device can be carried inconspicuously. In the solution according to the invention   1. known microphones which are inserted in the ear are used. External noise is thus screened in the ear and the microphone can also be used in a noisy environment; 2. the use of a base station close to the transmitter (e.g. on the body) and a wireless connection are provided.

Title: Method and device for controlling the reduced pressure characteristics of a medical aspiration device working with a suction phase and a relaxation phase
Inventor: NICOLAI WALTER
IPC: A61M1/06
Filed: 1989-05-23
Abstract: The invention relates to a method for controlling the reduced pressure characteristics of a medical aspiration device working with a suction phase and a relaxation phase, which comprises a suction and venting line extending between the aspiration device and a liquid collection vessel provided with an aspirator, in which introduction of air into the venting line and hence into the aspirator is blocked and/or adjustable or metered in a firmly predetermined manner at the end of the suction phase of the pump unit of the aspiration device and at the start of the relaxation phase until a freely selectable point in time but before the end of the relaxation phase. By this means, the corresponding device can be produced with little economic expenditure and space requirement and at the same time meets at least the same requirements as regards response, adjustability and functional reliability as the conventional devices, and permits reliable control of the reduced pressure characteristics even without use of mechanically scanned curve shape discs whose shape data correspond to the particular reduced pressure characteristics desired.

Patent DE-3939783-A1 (DE)
Inventor: HAIST HENRI
IPC: B65D79/02
Filed: 1989-12-01
Abstract: A threaded closure made by deep-drawing of aluminium for glass bottles under internal pressure, wherein the tightness after filling is to be determined via deformation changes on its upper closure surface 4, has a particular shape at its upper closure surface 4 for the purposes of greater deformation changes which can thus be registered more reliably. Directly after completion of the closure operation, the upper closure surface 4 is thus pressed a short way with its central region 7 into the interior of the glass bottle and can be deformed in such a way that the central region 7 can be pressed outwards under the subsequent effect of sufficient internal pressure. Such threaded closures are also particularly suitable for fully automatic control measurements. In the deep-drawing device, also specified, for a closing-head to make such threaded closures, a stop 13, held displaceably in the inner cutout 12 of a die 8, is to have a central pressing-on surface 15 which extends a short way beyond the base area 16 of the stop 13 and is arranged concentrically to the mid-axis 9 of the die 8. <IMAGE>

Title: Variation of tyre tread pattern to suit road conditions
Inventor: LIEBIG WILLI
IPC: B60C11/16
Filed: 1990-02-19
Abstract: A process is described which allows the tyre tread pattern to be varied according to the varying road conditions, esp. wet or icy surfaces. The negative effects of dirt and icing on the tyre are avoided and the changeover time is minimal. The main feature of the process is the ability to distribute the tractive effort over different parts of the tyre tread by using tyre pressure. A tyre can be adapted to icy road conditions by controlling the pressure inside a chamber in the tread area and below an area of special studs. The special chamber can be activated: (1) with the vehicle stationary or moving; (ii) rapidly; (iii) by manual or automatic controls, e.g. via sensors and wireless transmission of sensor pulses, are delivered through receivers and pulse guides to ignite gas cartridges.  An alternative method of activation uses compressed air in containers in the wheel and controlled by valves and lines. Control units facilitate the readaptation to changes in road conditions.
